EYE-SHIELD PROTEGTINGr-SFECTACLES.

Application filed April 21, 1913.

To all whom/it may concern Be it known that We, FREDERICK ll 'lnnson andNoam BOUHQULN, both citizens of the United States, residing at Reading,in the county of Berks and State of Pennsylvania, have invented certainnew and useful Iniprovenients in Eye-Shield Protecting-Spectacles, ofwhich the following is a specification.

This invention relates particularly to eyeprotecting spectacles.

A main object of the invention is to pro vide conveniently removablefolding side shields spring-engaged to the lens trainings and adapted toinclose-the temple ,gonnections when in position for use.

The invention is fully described in connection with the accompanyingdrawings, and the novel features are specifically pointed out in theclaims.

' Figure l is a rear view of spectacles e1n-. l o 1lying our invention.in preferred form, the temple and eye-shield on one side being shown inposition for use, and on the other folded against the inner face of thelens. Fig. 2 is a longitudinal section on the line 2+2 of Fig. 1.. Fig.3 is a cross-sectional view on the line 3--3 of Fig. 1. Fig. t indicatesa mmlitication.

The lenses 2, 2 as shown, are of large size and unusual thickness so asto provide ellicient protection for the eyes of the wearer againstcontacting material; and they are separated by a bridge bar 4tconnecting the lens-encircling 'lranies IL 5 so that the latter may bearranged to bear upon opposite sides of the nose for proper support.

h lens frame 33 is preferably formed, as shown, from a punched blank oi"sheet metal. which is shaped to cncii le the lens, and to provide incross-section a lens-edge engaging groove 30 and a flatiens-tace-contactingi flange 11 said lh-inge being provided withoppositely arranged inturned pivotcars i2, is for ccn'uccting the sideshield and with an intermediate temple-joint cud-piece H for the temple15. lhis {hinge the inner face of the lens, on the mar ial. portionthereoi',and serves to largely insure the wearer against vu ury due topossible fracture of the lens by coni l lies again tact ol. anysubstance with its exterior face.

Even if the lens be thus fractured the man "l" "'-l' lbith ginaiPuliulllll: or it an ac c. ietainec y e Specification of Letters Patent.

flange 11 as to prevent injury to the ivearer; While any contactingsubstance is'left free to glance ofi from the outer face of the lensinasmuch as this projects beyond the plane of the lens-edge-engaginggrooved portion of the framing. i danger of the lens being fractured inservice, ve provide for further security against inury to the wearer, byclamping between the inner face of the lens and the framing flange 11, awire screening 19 as indicated to'the right of Fig. 1 and to the rightin the crosssectional Fig. 2. Both the pivot ears 12, 12, andthe templejoint end piece '14, are ar' ranged .Within the marginal portion of theframe, 5, the side-shields 13, as hereafter described, being arranged toseat upon said marginal portion outside of said end-piece.

The side shields 13 are shaped as usual to close the space between thelenses and the face of the wearer, eaph comprising a semicircular basepiece and a triangularly Where there is special shaped piece 21 ofleather, Wire gauze, or the like secured thereto. The curved base piece.

20 is preferably made of metal, forming a relatively still but flexiblefr'ame-conpecting part adapted to be sprung into or out of engagementwith the pivot cars 12, 12 andtemple-joint end piece 14. The spread ends22, 22 of said base piece are provided with pivot eyes Which are adaptedto spring into' engagement With rigid pivot pins or trunnions 23 on theears 12, 12, so as to hinge the shield to the frame 5, but which areread ily sprung apart, normally, so as to permit disengagement of theshield when desired. When thus lunged to the frame 5 the curved shield13 extends around or outside bf the.

temple-joint piece 14; and the pivot-entl ortion of the temple 15, andisfree to fol in ward with the latter against the inner face of thelens, as shown to the right of Figs jacent portion of the temple 15, arecovered by the side guard 13 when in service, thus protecting the sameand presenting a neat appearance; and the guards are firmly retained inposition, yet may be readily disengaged and new ones substituted whendesired, thereby great v extending the satisfactory service of th;spectacle.

In the modification shown in Fig. 4 the lens-framing piece 25, with itsintegrally formed shield pivoting ears 12, is adapted for -use inconnection with an ordinary eyewire 26 by means of which it is clampedto the lens.

hat we claim is 1. In eye shield spectacles, the combination with a lensframing having shield pivot ears, of a removably hinged springframeshield having a trunnion engagement with said ears. 1

2. In eye shield spectacles, the combina- I tion with a lens framinghaving shield pivot ears and a temple joint piece", of a removablyhinged spring-frame shield having a trunnion engagement with said earsand adapted to be sprung into and out of engagement with said templejoint piece.

3. Eye shield. spectacles having temples and eye shields separatelyhinged thereto, the shields being arranged to inclose pivotend portionsof the temples when the parts are spread for-service, and to fold downupon the foldedtemples.

In eye shield spectacles, the combinationwith a lens framing, of a temple and a shield separately hinged thereto,said shield being. adapted to inclose the temple joint and having aspring engagement therewith." v 1 5. In eye shield spectacles, a sheetmetal lens-frame formed with a, Iensedge-engaging groove and havingoppositely arranged shield pivot ears, and a removably-hinged shieldhaving aresilient semi-circular base portion the spread ends of whichare adapted to be sprung into and out of trunnioned engagement with saidears.
